Other objects, advantages and meritorious $6. tures will more ful y appear from the following specification, claims, and accompanying draw.- in s, wherein:

Fig. 1 .is-an elevation of the window structure embodying this-invention;

Fig. 32 is a vertical sectional view partly broken away being a perspectiveof a part of the window assembly;

Fig. 3 is a horizontal sectional view takenon the line 3--3 of Fi 1;

Fig. 4 is a fragmentary perspective of the lower part of the window assembly as shown in Fig. 2 but with the sash removed;

Fig. 5 is a perspective similar to that shown in Fig. 2 but showing the two window sashes in the elevated position; and

Fig. 6 is a fragmentary perspective of a character similar to Fig. 5 but showing one of the window sashes reversed end for end as compared With Fig. 5.

This window assembly is designed primarily to be formed from sheet metal. It may be formed-of other suitable material. In the drawings two upright opposed complementary jamb members are indicated by the numeral l0. They are connected at the top by a header l2 and at the bottom by a sill member M. Each jamb member may be formed of sheet metal bent, as shownparticularly in Fig. 2, into channel shape. The channel may be received over a wood jamb member 18, as shown in Fig. 2. Each jamb member is provided with a sash guide channel side wall portion 20. This sidewall portion Ztlinay be formed by'a fold in the metal, as shown particularly in Figs. 2, 3 and 4. This side wall 2c forms the outer wall of the outer guide channel for the sliding sash which is mounted between the jamb members.

The sill member I 4 which connects the jamb members at the bottom is shown particularly in Figs. 2, 4 and 5 assha ped to provide a downwardly open channel portion which may, if desired, be seated over a wood strip 22. Such channel, howeven-mi'ght be closed at the bottom with a metal strip. This sill portion I4 is provided with an "inner side wall ledge 24, as shown particularly in Figs. 2, 4' and 5. This inner side wall ledge constitutes an abutment at the bottom against which a lower window sash may rest and be retained.

The header member i2 which connects the iamb members at the top may be formed of sheet metal folded upon itself to exhibit an Outer side wall portion 25, intermediate wall portion'23, and an inner wall portion 38,, all as shown particu' larly in Figs. 2, 5 and 6. ihe space between the wall portions .26 ,and .28 constitutes an outer header channel. The space between the "wall portions :28 and .30 onstitutes an inner {header channel. These header channels are adapted to receive the top rails of upper sash elements and frictionally engage them. They serve to help support the upper sash elements by such frictional engagement. These header channels have such a depth that the upper sash elements may occupy a closed position, as shown in Figs. 2, 5 and 6, and there still will be space above the top rails of the sash to permit elevation of the upper sash within the header channels for purposes hereinafter set forth.

Each jamb member ID is provided with a channel strip 32, as shown particularly in Fig. 4. This channel strip 32 may be secured by rails or the like 34 directly to the wood backing 18, Fig.

3. This channel strip 32 extends along the bottom half of each jamb member spaced inwardly from the side wall 20 so that the outer wall 36 of the channel member 32 forms with the side wall 20 an outer lower runway or guide. This side wall portion 36 is bent inwardly providing a marginal flange 38, as shown particularly in Fig. 4. Spaced between the edge of this marginal flange 38 and the inner side wall of the channel 32 is an inner lower channel guide, as shown particularly in Figs. 2 and 5.

This window assembly is adapted to accommodate two window sashes and a screen sash and to provide for permanent storage of these three sashes within the assembly so that it becomes a year-round assembly as hereinafter set forth.

In Fig. 2 there is shown an upper window sash indicated by the letter U and a lower window sash indicated by the letter L, and a screen sash indicated by the letter S. The lower window sash is disposed within the channel 32 within the lower half of the window. The upper window sash is disposed between the jamb members with its top rail received within the outer header channel and with its side rails resting against the outer channel guide walls 23 and with its bottom rail 48 superimposing the top rail of the screen sash S.

The bottom rail 4% is shown as formed of sheet metal shaped so as to exhibit a downwardly open channel 42. This downwardly open channel 42 is shown in Fig. 2 as receiving a top rail of the screen S. It fits thereover. This engagement of the bottom rail of the upper sash with the top rail of the screen and the engagement of the top rail of the upper sash within the outer channel of the header holds the upper sash against any lateral displacement. The upper sash is also supported in the elevated position.

The screen which is shown as resting at the bottom upon the sill member Hi and resting throughout its height against the outer channel wall 25 is held thereby in place and in the position shown in Fig. 2 is in what might be termed a stored position alongside the window sash.

The lower window sash mounted within the inner channels. 32- between the jamb members is provided with top and bottom rails of a particular construction for the purpose hereinafter described. I

The bottom rail to of the upper sash exhibits in addition to the downwardly open channel 42 an upwardly open inwardly offset channel 56, note Figs. 2, 5 and 6.

In Fig. 2 the lower sash is shown as having a top rail so folded upon itself as to exhibit an outwardly laterally offset downwardly open channel 50 which interlocks within the channel it of the bottom rail of the upper sash, as shown in such figure. This interlocking engagement forms a tight seal between the two sashes. The bottom rail of the lower sash shown in Fig. 2 is so shaped as to provide an inwardly laterally offset downwardl open channel part 52 which, as shown in Fig, 2, may serve as a handle.

If it is desired to employ the window assembly with the lower window space opened and closed merely by the screen, the lower window may be lifted out of the retaining channels 52. These channels extend only throughout the lower half of the jamb members as shown. When lifted out of the lower channels 52, the lOwer window may be placed alongside of the upper window with its top rail received within the inner channel of the header as shown in Fig. 5, and with its bottom rail seated within the channel 46 of the upper sash, as shown in Fig. 5. When so seated the channel part 52 overhangs the top of the screen so that the screen can be elevated only a very limited distance. It cannot be elevated sufiiciently to remove it or to permit unauthorized entry. In such position the arrangement is that which would be suitable for a lower floor storm and screen window assembly. 7

When the lower window is reversed end for end, as shown in Fig. 6, with bottom rail of the lower window seated within the channel 45 of the upper sash the screen then is in position, as shown in such Fig. 6, to be raised or lowered as desired. This arrangement might be suitable for an upper floor storm window assembly where it might be desired to elevate the screen to shake a dust mop or the like.

It will be seen that when the sashes are arranged as shown in Figs. 5 and 6, a seal tight joint is formed between the top rail of the screen and the lower rail of the upper sash.

When the sashes are arranged, as shown in Fig. 2, the lower sash can be readily elevated out of its channel 32. The upper sash maybe then lifted within the header sufficiently to clear the top of the screen and permit the bottom of the upper sash to be pulled inwardly laterally and said sash lowered out of the header. The screen may then be readily lifted out of its channel. When the sash elements are arranged, as shown in Fig. 6, the screen may be raised out of its channel 32. The lower sash may be lifted up into the header out of the channel 46 of the bottom rail of the upper sash and may be withdrawn laterally inwardly being lowered out of the header at the same time. The upper sash may then be dropped and withdrawn inwardly.

When the sash elements are arranged, as shown in Fig. 5, it will be apparent that the screen cannot be lifted except a small distance because the top rail of the screen will engage the channel 52 thereabove of the lower sash. The lower" sash may, however, be dropped sumciently to dis.- engage its top rail from the header and thereby permit its withdrawal inwardly laterally. After it has been removed the screen may'be readily lifted out of its channels and the upper sash may be removed.

When the screen is arranged as shown' in Fig. 5 or 6 and the upper sash U and lower sashL are arranged side by side in the upper half of the window frame as illustrated, the bottom of the channel 46 of the upper sash rests upon the upper end of the outer side wall of the lower inner guide channel 32. Figs. 5 and 6 show the top rail of the screen bearing snugly against the inner side wall of the channel 46 of the upper sash U; It is apparent, therefore, that the outer side wall of the channel 32 must support this upper s'ashi There is sufiicient flexibility in the assembly to permit assembly and disassembly to be carried out.
